Default Bought a 4890 1GB - How will my system do?

Hey guys,

I am upgrading from a 8800GT 512MB to the recently-released 4890 1GB.

I have the following specs, exclusive of the video card:

  • Q6600 Core2Quad @ 3.2GHZ
  • 4GB RAM
  • P35-DS3L motherboard
  • Enermax EG495P-VE Noisetaker 485W Power Supply
  • 1 x 200GB IDE Drive
  • 1 x 300GB SATA drive
  • 1 x 1TB SATA drive
  • 1 x DVDRW Drive
  • 1 x DVD-ROM Drive

I guess I have two questions:
  1. What will be the bottleneck you forsee in this system CPU? Video card?
  2. Is my Power Supply going to do the trick? If not, I can disconnect the DVDROM and the IDE drive, if that helps?
Thanks!

1. Since your Q6600 is Quad-Core and because it is overclockedo to 3.2ghz, it should not be a bottleneck at all for the 4890, and if so only an unnoticeable difference in FPS when gaming. If worse comes to worse see if you can squeeze another 1-400MHZ out of it, get a better HSF if you haven't already, etc.

2. Your PSU will positively, absolutely NOT do the trick. I would get a 550W bare minimum. If you unplug the IDE HDD and DVD-ROM drive it might do the trick, but then again chances of that are still small. If you want to have full-on functionality with everything you currently have running in your machine, a 600W would be ideal.

Like the other guys, I recommend that you upgrade your PSU to a far better one.

I am running a 4890 1GB together with a Q9450 @ 3.6GHz and 4 hard drives on a 750W PCP&C.

^^Ah, but your 750W might be a bit too much for your setup, Oversized Rooster. That PSU could easily handle a second 4890!

@Amorak: Definitely, Definitely, DEFINITELY get AT LEAST a 550W, even 550 is stretching it. Recommended would be 600-650W. HX620, Silencer 610, anyone?

The PCP&C 750 is often on sale online for a very reasonable price. In these days of 1000 watt+ units, I don't think 750 is too much.
Dam good power supply.

Get a better PSU, such as the Corsair HX620. It definitely won't provide enough juice for a 4890. Even if it does, I'd worry bout it.

What resolution are you gaming at? The resolution could also determine whether your CPU is a bottleneck or not.
